Opinions on replacing one tire

[Maquis]

I lost a tire due to road hazard. Tires are at about 1/2 tread. What are some opinions regarding replacing just the one, replacing a pair at the same end of the car, vs replacing all 4? I’m inclined to replace a pair.

My vote is 2 tires.

Unless the tires are more than 7/8, I tend to go with an axle pair at a time. The exception is when I can find a used or shaved tire that closely approximates the other three. ??

I had one tire replaced at 19 months, 19k miles. It's now 11 months later. So far, so good.

When it's time to replace the other three, I'll do all four.

I would usually just replace all four, as I literally just did day before yesterday.
Picked the car up on 8/5, took a screw in the shoulder last Wednesday. Summer tires were on it so I said let me get the all seasons now and save the other three to perhaps put back on next season after getting a replacement since there is less than 500 miles on them.
Anyway, I found this and sounds correct to me.

FRONT-WHEEL DRIVE AND REAR-WHEEL DRIVE VEHICLES
When replacing one tire: The new tire is paired with whatever tire on your vehicle has the deepest tread depth. Then, both tires are mounted on the rear axle.

When replacing two tires: The two new tires are mounted on the rear axle.

Also, if replacing only one or two tires, it is recommended that the tires are placed on the rear to prevent hydroplaning during wet road conditions.

FOUR-WHEEL DRIVE AND ALL-WHEEL DRIVE VEHICLES
Things are a bit trickier with four- and all-wheel drive vehicles. Even tiny differences in tire diameters on an axle, or between tires on different axles can lead to a glitch in the drivetrain system. Usually, all four tires are recommended to be replaced at once, but always check your vehicle manufacturer's recommendations for specific guidance regarding your vehicle.

You have too much wear to replace just one tire, but replacing two is fine.

Also, Discount Tire will have a Labor Day sale kicking in by Friday.

This is exactly correct. You never put the new tires on the front with older tires on the rear. Unfortunately, too many shops don't know this.

Or, I've used Unitedtire Free shipping and a warranty. So far no problems with any tire I've got from them. (I had to go this route because I'm still hunting down a wheel issue and didn't want to destroy brand new Mich's)

Thanks for the input.

And forget about tire rotation?

1st, you should replace the tires in a pair. I would never put two tires on the same axle with more than 3/32 difference.
2nd, you should always put the two new tires on the rear.
This may be hard to understand until you have driven on a tire manufacturer test track. Micheline has a very good test track. I have had the pleasure more than once. It is very informative.

 

[VaporTrails]

You have a FWD AND RWD, but they are not mechanically coupled like on a normal AWD. I would recommend two tires on the same motor if the tread depths are substantially different. And at 1/2 worn they are substantially different. New ones go on the back. Once they are worn in, normal rotation pattern.

I understand, ant totally agree - newer tires need to be in the rear. But after another 10K miles they are still newer, so will you do the normal rotation at this point? Or get a new pair and place it in the rear?

Isn't it better at some point, if you want to keep the car, replace all of them?

I agree with that line of reasoning. There is also a “hassle cost” of having your vehicle in the shop. I would definitely give more weight to replacing all four in my decision process.

However, different folks are in different situations. New tires are going to shave off some tread initially adjusting to the camber. They will never be the same, but they will get closer. Also, some of us are not getting full mileage to begin with….HVBJB testing and all. ?

 

[Maquis]

My wear patters have been very even. My initial plan is to put 2 new on the rear. In 12K, the fronts will have 40K, so put new on the rear and rotate the rear to the front. Now, there is only 12K difference, so go to normal rotation.

I won’t be pushing things like you do on a test track!
